To @ZZ whom it may concer-n..-

Beit known thatY LSPHI'LP H. FIELDING, a citizen of the United "States,residing at the city of New York, in the borough of Manhattan and Stateof NewYork, have invented vcertain new and useful Improvements in In-The complete details of construction will beV described with referenceto the accompany? ing drawings, in whichp Figure lis a side elevation ofmy improved device, and Fig. 2 a central section of the same. Referringto the drawings by letter, a is a block of insulating material whichserves as a base, to which are attached the conducting and supportingparts of a lamp-socket of any type. As shown, the socket isof the Edisontype, having the usual threaded shell a', at the bottom of which is acenter contact of which the lug a2 is an extension. Said lug leadsthrough an opening in the side of the shell, as shown, and carries abinding-screw d for securing one of the conducting-wires.

vIt will be understood that a lug of similar character, connecting withthe shell a', is located on the opposite side of the block aand carriesa binding-screw similar to as for the attachment of the otherconductingwire. These parts being of ordinary construction it is notconsidered necessary to illustrate them in detail. v

The block or base a may be of any suitable shape; but as here shownitconsists of a thick disk from one side of which a projection a4 rises.This projection is embraced upon oppbsite sides by a yoke-shapedmetallic frame b, having a tubular neck b', which is threadedexteriorly.` `The yoke is secured to the projection by a lateral boltb2, which forms a pivot affording slight lateral movement bey'tween theyoke and the base to allow the socket to settle itself within the shade,as will hereinafter appear. The conducting-wires l and 2 lead throughthis neck and yoke and, separating at the upper end of the extension 1a4, lead downward on each side thereof to the the shape of a lily. AThepart immediately surrounding the socket should be made of an interiorshape to conform to the shape of the socket, and thus prevent'relativemovements of the parts and provide a rigid structure. At the base lofthe shade there is a small opening, through which the neck b of thesocketpasses, and to secure the socket and Athe shade in fixed relationwith each other a sleeve e is screwed onto the projecting part of theneck b until it clamps against the edge of the opening in the base ofthe shade,

and to make a good fit at this point the lower socket must be secured byscrewing. Before the socket is thus secured, however, the conductingwires l and 2 have to be drawn through the fixture and secured to thesocket in the manner before described,- and if the socket is thendirectly screwed to thefiXture the wires will be twisted,wh-ich isundesirable. To avoid this, I interpose `the coupling g, which isprovided with an internal threaded passage adapted to screw onto thenipple f and also with an annular flange g', adapted tol pass freelyover the upper portion of the sleeve c. The wires are passed throughthis coupling before they are passed through the neck b' to the socket,and after the slack in the Wire has been taken up by drawing it backwardthrough the fixture F the coupling g is screwed onto the nipple withoutrotating the sleeve e. When the coupling is fully in in place, thescrews g2 and g3 in the flange g are set up to engage with the sleeve e,the sleeve being provided with an exterior annular groove e to receivethe end of the screw g2, which prevents the separation of the two partse and g. The screw g8 passes through the sleeve e and binds against thethread on the neck b', thus not only securing the parts e and gtogether, but also preventing the unscrewing of the sleeve on the neckand the consequent loosening of the joint between the bevel edges of thesleeve and shade. When thus in place, a lateral screw g, carried by thecoupling g, isset up against the nipplefto prevent the coupling fromturning in either direction. This last screw therefore prevents theentire socket from being rotated, which might otherwise take place to aslight degree when the lamp is screwed into and out of the shell a'.

Having described my invention, I claiml. The combination of thecontacts, terminals and lamp-holding devices of an incandescent-lampsocket, with a lamp-shade detachably connected with said parts andprovided with an inclosing casing therefor and having integral extendingportions forming the shade or reflector, substantially as described.

2. The combination of an incandescent- 55 lamp socket, a shade thereforhaving an opening, a. tubular neck projecting from the socket throughand fitting said opening and a clamping-sleeve on said neck for holdingthe shade.

3. The combination of the contact-termi- 4o nals and lamp-holdingdevices of an incandescent-lamp socket, a lamp-shade provided with anintegral inclosing casing for said parts of the socket, said shadehaving an opening, a tubular neck projecting from said 45 socket partsthrough and fitting said opening and a clamping-sleeve on said neck forholding the shade, substantially as described.

It. The combination of a lamp-socket, a supporting-bracket having athreaded nipple, a 5o neck extending from the socket and a coup` linghaving a threaded part adapted to engage with said nipple and meansforattachment to said neck, substantially as described.

In witness whereof I subscribe my signa- 55 ture in presence of twowitnesses.

PHILIP H. FIELDING.
